Predrilling

Yep. I use a lot of oak for framing temporary sheds like in the
photos. If I don't predrill the lag screws break off when I remove
them later. I salvaged the oak beams from pallets for kitchen counter
sheets and use them for rafters. The wood is almost as hard as 1980's
Chinese cast iron.
